Identity-based encryption and digital signature schemes using extended chaotic maps

SK Hafizul Islam

Abstract: This paper designed a new extended chaotic map-based Identity-based encryption (ECM-IBE) scheme and Identity-based digital signature (ECM-IDS) scheme using extended chaotic maps. The security of the ECM-IBE scheme is based on the hardness assumption of chaotic maps-based decisional Diffie–Hellman (CDDH) problem, whereas the ECM-IDS scheme is secure based on the difficulties of chaotic maps-based discrete logarithm (CDL) problem.

Category / Keywords: public-key cryptography / Chaotic maps; Identity-based encryption; Digital signature; Hash function; Diffie-Hellman problem.
